§ Miss Richardsonasked the Secretary of State for the Home Department how many closed circuit television cameras are in operation in London other than those solely devoted to central integrated traffic control; where these cameras are located: whether they are in constant operation and if not on what occasions they are used; what is the cost of using the cameras; what kind of equipment is used; what type of lenses are used; what happens to the film which is taken; and if he will list the occasions when these cameras have been used from 1st January 1977 to date.
§ Mr. Merlyn ReesMy Department has no information about the use of such equipment where it is privately owned or used by public services for which I have no responsibility. So far as the Metropolitan Police are concerned, the Commissioner informs me that nine closed circuit television cameras are available in London in addition to those primarily intended for central traffic control. They may be installed on fixed or temporary sites and are used as occasion arises to facilitate crowd and traffic control. Any film taken may be used subsequently for training purposes. The equipment and lenses are chosen from models that are commercially available. The annual cost of maintenance is approximately £6,500. Closed circuit television is also used in Metropolitan Police training establishments. A comprehensive list is not available of all the occasions on which such apparatus has been used.
